The main advantages of laser cutting technology in automobile manufacturing Laser cutting machines have been widely used in the automobile manufacturing industry, and play an irreplaceable role in other CNC cutting equipment. Its main advantages are as follows:
1. Applicable to a variety of material accessories
   Automotive materials include low-carbon and low-alloy steel, high-strength steel, atmospheric corrosion-resistant steel, ferritic stainless steel, austenitic stainless steel and aluminum alloy, etc. All laser cutting equipment can process it, and its processing range can cover almost all materials in automobiles. pieces.

2. High machining accuracy
   Laser cutting equipment has higher processing precision than other cutting equipment, and can meet the processing requirements of high-precision accessories.

3. narrow slit width
   Small slits are beneficial to reduce the spacing of accessories, improve material utilization, and produce less cutting slag during cutting.

4. High utilization rate of materials
   When cutting accessories, you can cut different accessories with the same thickness and material, and make full use of the leftovers of the raw materials.
5. Low cut roughness value
   Laser cutting equipment, when cutting accessories of the same material, has a lower cutting roughness value than other equipment. In the automobile manufacturing industry, the cross-section roughness of workpieces processed by different laser cutting machines is significantly different, and the cross-section roughness value of laser cutting is low.
6. Small heat affected zone
   During the laser cutting process, the edge of the material to be cut will generate a heat-affected zone due to heat. However, compared with other processing methods, laser cutting has lower energy concentration and heat input. Compared with fine plasma cutting and flame cutting, the heat-affected zone is relatively small and the heat input is small. It is suitable for ferritic stainless steel that is easy to grow grains and easy to quench. High-strength steel with a hard tendency is of great significance and is conducive to improving the quality of welds.

7. Low-cost laser cutting for small batch production
   In mass production, the process of mold blanking is selected for processing, and the cost of making molds is evenly distributed to each part in mass production, and its production cost is low. However, if it is a small batch production, the die blanking process is adopted, not only the die production cycle is long, and the timeliness of parts processing cannot be met, but the die manufacturing cost is evenly distributed to each part, and the processing cost is relatively high.
   Therefore, CNC cutting is generally used for processing. When CNC fine plasma cutting is used, due to the weak perforation ability of plasma cutting, the low cutting precision and the poor forming quality of the hole, another drilling process needs to be added, and a drilling mold needs to be made. Not only the processing time is longer, but the cost is also higher. Laser cutting can ensure that parts are formed at one time, which is beneficial to improve the timeliness of parts processing, and is suitable for small batch production. How to choose the cutting process needs to be comprehensively considered according to the size, shape, cost and accuracy requirements of the accessories. When the size of the accessories is small and the shape size and positioning size of the holes are required to be high, it is more economical to use the laser cutting method.

   With the changes in the automobile manufacturing industry and the global economic integration, various automobile manufacturing enterprises have transformed from the original single, large-scale national railway car production to small-scale, multi-variety export vehicles. This transformation has also brought revolutionary changes to the manufacture of auto parts. The original sheet metal processing equipment such as shearing machines and punches are used less and less frequently. CNC fine plasma cutting machines, CNC flame cutting It has been replaced by CNC flexible equipment such as machine and laser cutting machine. Among them, laser cutting equipment has an irreplaceable role because of its advantages of processing high-precision, small-size, complex shape accessories, and being able to process a variety of materials.
